Fire Service Meters
From the single-family home to a massive manufacturing structure, the sprinkler system relies on the full-rated capacity of the water meter to do its job. For more than 100 years, Mueller has been the proven leader in fire line meter design. These vigilant meters personify the reason your customers want fire sprinkler systems in the first place, bringing peace of mind.
FM3 with Bypass
The Mueller’s FM3TM fire service meter is designed for combined fire service and domestic water where a single supply line supports both fire and domestic or process needs. The meter may be utilized in automatic sprinkler systems and fire service, as a master meter for an entire water system, as a master meter for zoned systems, and for domestic or processed water where accuracy across a broad range of flows is critical. The FM3 meter eliminates the need for secondary service lines, saving time and reducing installation expenses, and is compliant for all UL®, FM®, NSF-61 fire service meter standards.
The Ultimate Litmus: A UL Stamp
Mueller’s RFM meter was the first residential fire meter on the market to carry the prestigious Underwriter’s Laboratory (UL) listing and is widely accepted as assurance of system component reliability. UL subjected the RFM meter to accelerated aging, heat extremes, leaks, pressure loss, burst pressure and long-term durability tests to verify full flow reliability and long-term accuracy. Designed for use in residences with fire protection systems or for combination domestic plumbing / fire service, RFM meters are available in sizes from 3/4″ to 2″.
Keeping Leaks in Check
Theft and leaks compromise the integrity of a fire system. Mueller detector checks are spring-loaded devices that keep a check on flow irregularities, so you can tell if water is “slipping by.” Rugged and reliable, they are designed to reduce pressure loss, ease maintenance, and enable an unobstructed flow through the main line. Bypasses are available with Mueller positive displacement or vertical turbine meters.
Fire service meters used in AMI applications work seamlessly on the Sentryx platform.
